I found on on April 9th that I was pregnant. I had an ultrasound to see how far along I was but the doctor told me it was too soon to determine because he couldn't see anything. I had my last period on March 7th 2009. I had sex with my ex boyfriend on Feb. 24th. I started having sex with my new boyfriend on March 17th and on. I'm confused on who my baby's father is. Someone help!
